Sculptris is a supercool free sculpting tool. You can download it here from Pixologic.
Much like ZBrush, Sculptris is a solid-body sculpting tool. Since it has an export function, we can use it for 3D printing too! Unfortunately at this stage we don't yet support OBJ files, so there's a couple of easy hoops you need to jump through to get your design ready.
First export your sculpt as an OBJ file:
Then you'll need to open up Meshlab, to convert the OBJ to STL. You can download Meshlab here.
The Meshlab Part is super easy:
- Open the OBJ file you exported from Sculptris
- Save it as an STL file.
NOTE: If anyone knows how to do this in MeshLab (and therefore eliminate this last step) I'd love to hear it!
Open up your new STL file in Netfabb, and hit F5 for Platform Overview:
Make special note of the L x W x H dimensions, as well as the volume. You can then use the scale tool: to scale your part to the size you want.
Once you're happy with the size of the part, just right-click it and choose Export part - as STL (Binary).
